Brown sugar glazed stuffed salmon pairs rich salmon fillets with a creamy spinach-and-cream-cheese filling and a sweet-savory glaze. The salmon is butterflied, filled, then baked until flaky; a little Dijon and lemon balance the brown sugar so the finish tastes rounded rather than candy-sweet.
Ingredients
- 4 skin-on salmon fillets, about 6 oz (170 g) each and 1 to 1¼ inches (2.5 to 3 cm) thick
- 4 oz (113 g) cream cheese, softened
- 1 cup (30 g) packed baby spinach, finely chopped
- ¼ cup (25 g) finely grated Parmesan cheese
- 1 tablespoon (15 ml) mayonnaise
- 1 small garlic clove, minced (about 1 teaspoon)
- ¼ teaspoon fine salt, plus more to season the salmon
- ⅛ teaspoon black pepper, plus more to season the salmon
- 2 tablespoons (28 g) packed light brown sugar
- 1 tablespoon (15 ml) Dijon mustard
- 1 tablespoon (15 ml) lemon juice, divided
- 1 teaspoon (5 ml) olive oil, for the baking dish
Instructions
- Heat the oven to 400°F (200°C). Lightly oil a small rimmed baking dish. Pat the salmon dry with paper towels. With a sharp knife, cut a pocket lengthwise into the thick side of each fillet, stopping before you cut through the opposite side or ends. If the fillets are thin, make a shallow slit rather than trying to create a large pocket.
- In a small bowl, mix the cream cheese, spinach, Parmesan, mayonnaise, garlic, ¼ teaspoon salt, and ⅛ teaspoon pepper until evenly combined. Divide the filling among the pockets, pressing it in gently without packing them tightly. Some filling may remain at the opening; that is fine.
- Set the fillets in the dish skin-side down, with a little space between them. Season the exposed salmon lightly with salt and pepper. In another small bowl, stir together the brown sugar, Dijon, and 2 teaspoons of the lemon juice. Brush the glaze over the tops of the salmon, keeping most of it off the filling so it can brown instead of run into the dish.
- Bake for 14 minutes, then check the thickest part of the fish with an instant-read thermometer, inserting it into the salmon rather than the filling. Continue baking as needed, checking every 2 minutes; depending on thickness, the salmon usually takes 14 to 20 minutes. USDA FSIS lists 145°F (63°C) as the safe minimum internal temperature for fish. The center should look opaque and separate easily into flakes, and the thermometer should reach that temperature.
- If you want a darker glaze, broil for 1 to 2 minutes after the fish is cooked, watching continuously because the sugar can burn quickly. Rest the salmon for 3 minutes, then drizzle with the remaining 1 teaspoon lemon juice and serve. Total cooking time, including optional broiling, is about 22 minutes.
Tips
- Choose fillets of similar thickness so they finish at roughly the same time. A thermometer is more reliable than judging doneness by color alone, especially with a stuffed center.
- Soften the cream cheese before mixing for a smooth filling. If using frozen spinach, thaw it completely and squeeze out as much water as possible; excess moisture can make the filling loose and watery.
- For a milder glaze, use 1 tablespoon brown sugar instead of 2. If you do not have Dijon, use an equal amount of smooth yellow mustard; the flavor will be milder and less tangy.
- Do not overfill or force the salmon pockets shut. Filling can expand and escape during baking, and a small amount spilling into the dish does not affect food safety.
Serving Suggestions
Serve the salmon straight from the oven with rice, roasted baby potatoes, or couscous to catch the savory-sweet juices. A crisp green salad, steamed green beans, or roasted broccoli gives the plate a fresh contrast. Add lemon wedges at the table for anyone who wants a brighter finish; extra salt is usually best added only after tasting because Parmesan and the glaze already season the fish.
Variations
For a different filling, replace the spinach with ½ cup (75 g) finely chopped sautéed mushrooms, cooled before mixing. They bring a savory, earthy flavor, but should be cooked first so they do not release excess liquid inside the salmon. You can also swap the Parmesan for ¼ cup (25 g) crumbled feta; feta makes the filling saltier and tangier, so reduce the added salt.
For a spicier glaze, stir in ¼ teaspoon smoked paprika or a pinch of cayenne. For a more citrus-forward version, add ½ teaspoon finely grated lemon zest to the cream-cheese mixture. If your fillets are too thin to cut pockets, place the filling between two thinner pieces of salmon and secure the edges with toothpicks, removing them before serving; check that the center reaches the same safe temperature.
Storage and Reheating
Refrigerate leftovers within 2 hours of cooking in a covered, shallow container. Cooked salmon keeps for 3 to 4 days in the refrigerator. For longer storage, freeze it in a tightly sealed freezer-safe container for up to 2 months for best texture; thaw overnight in the refrigerator. The filling may soften after thawing, but the salmon remains suitable to reheat if handled safely.
Reheat gently in a covered oven-safe dish at 300°F (150°C) until the center reaches 165°F (74°C), the safe temperature for reheated leftovers. A microwave also works: use short bursts at medium power, covering the salmon to limit drying, and check the center with a thermometer. Reheating can make salmon firmer, so warm only the amount you plan to eat.
Frequently Asked Questions
Can I prepare stuffed salmon ahead of time?
You can mix the filling up to 1 day ahead and keep it covered in the refrigerator. For the best texture, cut and fill the salmon shortly before baking; if you assemble it in advance, refrigerate it promptly and bake within 24 hours. Do not leave raw fish at room temperature while preparing other dishes.
Can I use frozen salmon?
Yes. Thaw it completely in the refrigerator, then pat it very dry before cutting pockets and adding the filling. Partly frozen salmon cooks unevenly, and surface moisture can prevent the glaze from adhering well.
How can I tell when stuffed salmon is done?
Check the thickest part of the salmon with an instant-read thermometer, avoiding the filling. Fish is safely cooked at 145°F (63°C), the USDA FSIS minimum. The flesh should also be opaque and flake easily; visual cues are helpful but do not replace the temperature check.
Can I make this without cream cheese?
Use an equal amount of soft goat cheese for a tangier filling, or use ricotta mixed with the Parmesan. Ricotta is looser, so drain it briefly in a fine-mesh strainer and expect a softer filling that may spill more easily.
Can I cook the salmon in an air fryer?
Possibly, if the fillets fit in a single layer with room for air to circulate. Air fry at 375°F (190°C), beginning to check after about 10 minutes; timing depends on the appliance and fillet thickness. Confirm 145°F (63°C) in the thickest part and avoid overcrowding, which can lead to uneven cooking.
Why did the glaze become dark before the salmon finished cooking?
Brown sugar can scorch under high heat, especially near a broiler. Bake the salmon on the center rack and skip broiling if the glaze is already dark. If the tops brown too quickly during baking, loosely tent the dish with foil and continue cooking until the salmon reaches 145°F (63°C).
